Internets of Interest:1 Apr 11

But Wi-Fi performance can leave much to be desired. Throughput is hampered by backwards compatibility, microwave popcorn, and security cameras, and most seventh graders can accurately pitch a note out of range of the average access point. Plus, only anointed wizards possessing dark knowledge have the ability to put together a successful wireless LAN. The market is ripe for some new thinking, but multiple spatial connections, a switch to 5 GHz, and the removal of load-bearing walls haven’t been successful

Data Domani, a division of ETC, added, ìwe are implementing FCoTR and VATRI support into our line of storage arrays. †This will enhance the ability for vSphere 5 to do backups, restores and replication of the backups. †The FlexIO modules for FCoTR and the VATRI plugin will be released in May at our ETCWorld conference, with parts shipping in June of 2012.î

FCoTR continues to grow. I’m getting that feeling the FCoE has come to the game too late and with the wrong approach. Now the VMware is rumoured to offer support, well the game might be over.

YouTube – Aerohive…Now with Rainbows – Aerohive are doing a better job of communicating their controllerless networking architecture here with the liberal use of rainbows. Interesting approach to a difficult topic now that Openflow is promoting controller based networking in new ways.

RFC 1149 does not specify the use of any link layer tag such as an
Ethertype or, worse, an OSI Link Layer or SNAP header [RFC1042].
Indeed, header snaps are known to worsen the quality of service
provided by RFC 1149 carriers. In the interests of efficiency and to
avoid excessive energy consumption while packets are in flight
through the network, no such link layer tag is required for IPv6
packets either.

Some fine work here to ensure that RFC1149 is updated for IPv6. The gold standard reference for tenders to check vendor compliance is now IPv6 ready.

Broadcasting is a technology that has been largely discarded in favor
of technologies like multicast. This document builds on RFC 919 and
describes a more efficient routing mechanism for broadcast packets
destined for multiple Local Area Networks (LANs) or Metropolitan Area
Networks (MANs) using an alternative link layer. It significantly
reduces congestion on network equipment and does not require
additional physical infrastructure investment.

Probably shaking up the the data centre fabric market. This RFC bears close monitoring.

This is a surprise, but Cisco has announced the end of life of the 6500 switches that we all know and love. †Usually Cisco gives a platform a few more years after they decide to retire it, but the schedule only gives the 6500s one more year of service. †Iím sure this goes back the success and recent expansion of the Nexus line of switches.

The best known product for traffic manipulation is likely F5?s legendary iRules, but other vendors have similar capability such as A10?s aFlex. Essentially, this puts an application development platform. Typically this is done with a standard programming language, such as a modified TCL for iRules and aFlex.

The ASA module for the 6500 finally arrives. About two years later than expected. The question of whether it will be bought in sufficient numbers now that the C6500 is, for practical purposes, history mean that it may not last long. Cisco will kill products that do not sell enough.

HP is rolling out IPv6 support in stages with the goal of ensuring a smooth transition and deployment where IPv6-updated applications can take advantage of IPv6, without breaking existing applications.

I would point my attention to RFC 5984, too. Extra Sensory Perception is indeed great way to solve latency problems with networks, as it’s not dependent on underlying physical limitations (like speed of light). Some media even support negative latency with PPG (Precognitive Packet Generator).

A bi-weekly newsletter on a network human in IT Infrastructure.

IT Infrastructure is like a puzzle with hundreds of pieces. Some pieces are hardware, some are software and some are business processes. But the most important pieces are the people who design, deploy and operate the technology. Some news, links, opinions. Not too serious and a people focus.
